No extra charge for the pickups, or no extra charge for putting them in if you provide them? there's plenty of good pickups out there... i'd suggest not sticking gibson's in there, because alot of what you're paying for is the name "gibson"

if you want classic humbucker tone, go with seymour duncan. if you want something innovative, there's lace (their dually sensor pickups are best when installed with push/pull pots... ask your luthier about those...) and they've also got "hemi humbuckers" (they're like a cross between a humbucker and a p90 sound...) then they've got alumitones (one of the biggest innovations in pickup design since the humbucker...)
and there's q tuner... they've only got 1 model really, adapted for single coil, humbucker, and 7 string humbucker formats. it sounds acoustic, but it's a direct drop-in completely passive replacement for regular guitar pickups. (they don't have a p90 replacement though...)

I'm sure there's some other really neat, innovative pickup designs out there that i don't know about... most people just go with regular humbuckers, or if they have a guitar with single coils, they'll get hum-free single coils... which, in my honest opinion, isn't really bright... they could be trying all sorts of neat, new sounds... but instead they settle for the same tones that everyone has gotten before. so much for innovation... (though there's no problem with the tone that so-and-so the big skilled guitarist that's sold millions of albums and whatnot, I'd rather become the next one than a copycat...)
